Effective protocol for continuous pericapsular nerve group block in femur fracture patients undergoing hip surgery: two case reports

Abstract

Pericapsular nerve group (PENG) block was introduced as an effective way to control postoperative pain in patients who have undergone hip surgery. Therefore, we would like to discuss how to perform PENG block accurately on the basis of two cases, both of which involved hip fracture patients. Ultrasound-guided continuous PENG block was performed, and postoperative pain was adequately controlled in both cases. To mount the catheter in the correct position, it should be inserted after the needle enters at the lowest angle possible. If it is confirmed that the psoas tendon is pushed upward without an increase in injection pressure during drug injection, an accurate continuous PENG block has been achieved. We also analyzed fluoroscopic images to determine how the drug spread, and we observed that the drug spread around the hip capsule along the iliacus and psoas muscle.
